DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole, and more particularly to a shoe sole suitable for elderly people with reduced walking function.

[0002]

2. Description of the Related Art Excessive supination (overspination) of a foot when walking with an O-leg, which is considered to be more common in the elderly.
As a footwear to prevent swelling, there is a thing which provided the arch support which was gradually raised on the upper surface from the inside of the sole to the outside step part (the part corresponding to the first wedge bone to the cubic bone) by the actual fairness 6-31293. Proposed. However, in this type of footwear, the weight load during standing is simply moved statically from the outside of the long axis of the sole (the axis corresponding to the long axis of the foot) in the long axis direction of the sole. In the dynamic walking process, normal walking could not be supported.

[0003] In normal adult walking, two medial and lateral vertical arches along the longitudinal direction of the foot, the medial arch from the calcaneus to the head of the first metatarsal and the calcaneus, An outer longitudinal arch to the fifth metatarsal head, two transverse arches in the lateral direction of the foot, a first transverse arch from the first wedge bone to the tip of the cuboid bone, and a first middle arch. The second horizontal arch of the ball section from the head of the foot bone to the head of the fifth metatarsal bone walks while absorbing the landing impact pressure due to weight load. In the walking process, the weight load is first applied to the back of the heel while being prone from the outside to the inside of the heel, and then gradually stepping forward from the back of the heel along the back of the foot in the longitudinal direction of the foot. Moved while turning around
On the back of the ball portion of the finger, that is, the back surface of the joint between the fifth metatarsal bone and the fifth base phalanx, the foot is turned and the foot is strongly stepped on.
It is moved by stepping on the ground while rolling on the back of the ball joint portion of the finger, that is, the back surface of the joint portion between the first metatarsal bone and the first base phalanx, and then warps the first base phalanx and the first distal phalanx. Walking while repeating the process of strongly grasping the ground on the back surface of the first distal phalanx (first finger) while kicking and kicking the ground with the first to fifth fingers, especially the 1.2.3 finger, It is said to be so-called "tilting walking".

[0004] However, the knee of a human leg is bent outward (O-leg) due to aging, the center of gravity of the body weight at the time of standing is located inside the knee, and the weight load concentrates on the outside of the sole when walking. This is combined with two vertical arches due to the deterioration of the function of the leg muscles and ligaments due to aging, and two flat arches, and the flattening of the two horizontal arches makes it impossible to sway, and the weight load when walking is reduced. The heel part is moved linearly from the outside of the toe to the outside of the toe, and when walking, loses balance and stumbles, or the stepping part is excessively overturned (overspination) and falls outward. It is said that it is easy to do.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a shoe sole capable of promoting gait walking in a series of dynamic walking steps, maintaining walking balance, and preventing a stumbling, a fall in an outward direction, etc., during walking. It aims to provide soles for the elderly.

[0006]

According to the present invention, a sloping portion a gradually thinning from the heel portion 1 to the stepping portion 3 is formed on the rear side 11 of the heel portion from a gradually thickening portion from the inside 111 to the outside 112 thereof. The heel support b, which is adjacent to the heel support b, is not stepped on from the heel center side 12 to the outer side center side 222, and is gradually thinner toward the tip and has a tapered shape such as a wing shape. And an outer arch support c having a gradually thicker inclined portion from the side of the long axis L of the sole corresponding to the long axis of the foot toward the outer side 22 of the sole.
At a certain distance from the outer arch support c at the stepping portion 2, the inside of the half-moon shape gradually rising from the long axis L side of the sole corresponding to the long axis of the foot toward the stepping portion inside 21. The arch support d is formed on the upper surface of the sole of the sole 3 and the toe spring θ (when the sole is level with the floor, the sole of the toe of the sole and the floor). The shoe sole having an angle θ (also referred to as toe rising) of 6 to 20 degrees is the invention of claim 1.

[0007] In the present invention, the shoe sole means any one of an outer sole, a midsole, an insole, and an insole, or a combination of two or more of these. These are made of materials usually used for these soles, such as rubber, PVC, EVA, polyurethane and the like. In order to reduce the weight of the shoe sole from the heel portion to the step portion, a slim, ie, hollow portion may be provided in the heel portion. In the present invention, the toe spring θ is set to 6 to 2
The reason for limiting to 0 degrees is that if the tous pudding θ is less than that, chipping and kicking operations during the walking process cannot be performed smoothly and it is easy to trip, and if the toe spring θ is more than that, stepping on the walking process This is because there is a drawback that the gait becomes unstable and the walking balance easily collapses. In particular, as a shoe sole for elderly people with a reduced stride and no walking function with no vertical movement, setting the toe spring θ to 9 to 17 degrees is more desirable from the viewpoint of walking stability.

According to a second aspect of the present invention, in the first aspect of the present invention, the stepping portion support e is formed by a depression e ′ formed on a side of the stepping portion 3 corresponding to the ball joint of the first finger. When stepping on the ground, that is, when the weight load moves from the ball joint of the fifth finger to the ball joint of the first finger, the ball joint of the first finger falls into the depression e '', and the step on the foot By inwardly tilting, the rolling of the foot at the tread portion 3 is promoted, and the overspinning of the foot at the tread portion 3 is prevented. In the invention according to claim 2, if necessary, an elastic material such as incompletely crosslinked urethane foam, rubber, EVA, PVC or the like is added to an indented e ″ portion by foaming and crosslinking. If a shock absorbing material composed of a compressible deformable viscoelastic foam or the like is inserted, the compressive deformability prevents the ball joint portion of the first finger from dropping into the depression e ″ to hinder walking. It is possible to alleviate the maximum impact pressure applied to the ball joint portion of the first finger during the gait, and to prevent the pain and obstacle of the ball joint portion of the first finger.

According to a third aspect of the present invention, in the first aspect of the present invention, the stepping portion support e is provided from the ball joint of the first finger of the stepping portion 3 to the side corresponding to the ball joint of the second finger. When the foot load is going to move from the ball joint of the fifth finger to the ball joint of the first finger to the ball joint of the second finger,
The depression e ″ causes the ball joints of the first and second fingers to fall into the depression e ″, so that the stomping part of the foot is tilted inward to further promote the rolling of the foot and the foot at the stomping part 3. Overspination is prevented. In addition, even if it is not the O leg, in the case of the elderly, in many cases, it is not possible to sway together with the lowering of the vertical arch and two horizontal arches due to deterioration of the function of the leg muscles and ligaments due to aging,
When walking, the weight load is easily linearly moved from the center of the heel to the center of the stepping portion, and the maximum weight load during stepping is easily concentrated on the ball joint of the first finger.
It is said that the pain and disability of the finger's bow joint are severe, but in the invention of claim 3, the maximum weight load at the time of stepping is distributed to the ball joint of the first finger and the ball joint of the second finger. The pain and disability of the bow joint of the first finger can be reduced. In the invention of claim 3, if necessary, a shock absorber foam made of a compressible deformable viscoelastic foam or the like may be inserted into the recess e ″ portion, as in the case of the above-described stepping and walking. The maximum weight load (impact pressure) applied to the ball joint of the second finger from the ball joint of the first finger corresponds to the ball joint of the first finger and the ball joint of the second finger of the stepping portion 3 Can be dispersed and absorbed by the shock-absorbing foam inserted in the recess e '' part provided in the part to be worn, preventing pain and disability of the ball joint part of the first finger, which is considered to be common in elderly people I can do it.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the stepped portion support e is constituted by an inclined portion e ′ ″ which is gradually formed from the inner side 31 to the outer side 32 of the stepped portion 3. By doing so, when the ball joint of the fifth finger lands at the time of stepping on, the inclined portion e '''
The movement of the weight load of the finger to the ball joint portion, that is, the rolling is promoted, and the overspinning of the foot at the stepping portion 3 is prevented.

According to a fifth aspect of the present invention, there is provided a shoe sole according to the first aspect of the present invention. An outside counter f whose tip extends to the inside tip side 131 of the heel portion at the portion, and an inner arch stabilizing piece g is formed around the outer periphery of the inside 21 of the portion adjacent to the outside counter f to further walk. In this case, the landing stability from the heel to the stepping portion can be improved. The outside counter f and the inner arch stabilizer piece g may be formed integrally with the shoe sole or may be formed separately.

According to a sixth aspect of the present invention, in the shoe sole according to any one of the first to fifth aspects, the contact surface at the rear side 11 of the sole of the sole and the tip side 41 of the toe is formed of a smooth design h. The landing property of the foot behind the part and the kicking action at the toe are smooth.

According to a seventh aspect of the present invention, in the shoe sole according to any one of the first to sixth aspects, the rear back surface 113 of the heel portion is cut obliquely with respect to the ground contact surface, so that the initial landing stability during walking can be obtained. Is achieved.

In the present invention, if necessary, a metatarsal support, a so-called metatarsal pad, may be formed on the upper surface of the sole corresponding to the second metatarsal body to the fourth metatarsal body. ,
In particular, for a wearer whose second horizontal arch is flattened, the maximum weight load concentrated on the ball joint portion, particularly the ball joint portion from the first finger to the second finger, when stepping on the metatarsal bone body behind it. Since it is possible to disperse the joints between the first finger and the second finger, pain and obstacles at the ball joint of the first finger to the second finger can be reduced.

[0015]

Since the sole of the present invention is constructed as described above, the two vertical arches and the first horizontal arch of the foot are formed by the semi-lunar inner arch support d and the outer arch support c. When a person who is supported and has O-legs wears the shoes with the soles and walks, in the walking process, when the outer side 112 first lands on the heel part 1, the weight applied to the sole by the heel part support b The load is moved to the inside heel portion 111 to promote the pronation of the heel of the foot, and thus the landing stability of the heel at the beginning of walking is maintained. Next, the weight load to be applied to the sole is to be moved from the heel portion to the diagonally forward inner arch support d direction through the heel center portion by the inclined surface a, but the semicircular inner arch support d Excessive pronation (overpronation) is suppressed by the protruding portion of, and at the same time, excessive supination (overspination) is suppressed by the inclined surface in the short direction of the outer arch support c, and the inclined surface a and the gradually tapering thinner Is guided along the inclined surface in the longitudinal direction of the outer arch support c, and passes between the inner arch support d and the outer arch support c to the ball joint back surface of the fifth finger.
Moved with the foot out of the way. Then, the weight load of the sole that reaches the back surface of the ball joint portion of the fifth finger is moved by the treading portion support e while rolling to the back surface of the ball joint portion of the first finger, and the ground is firmly trampled. In the toe portion, the toe spring θ of the shoe sole is set to 6 to 20 degrees, which is higher than that of a normal shoe sole. .3 fingers can be kicked smoothly,
Fanning walking is promoted. Therefore, even in the walking of the elderly, the walking balance is maintained by a series of dynamic walking steps, and the walking does not fall or fall outward.
